RadioShack stores in Port Huron, Fort Gratiot, Marine City and Richmond are on a list of stores expected to close.

The company filed for bankruptcy last week and plans to close more than 1,700 stores nationwide, with about 50 of those in Michigan.

The stores slated for closure are expected to offer liquidation sales.

The St. Clair County stores expected to close are at 3552 Pine Grove Ave., Port Huron; in the Riverside Plaza, 6744 S. River Road, Marine City; 67342 Main St., Richmond; and in Birchwood Mall at 4350 24th Ave., Fort Gratiot.

All four location managers were not able to comment.

A list of the expected store closings nationwide, as well as more details about the bankruptcy filing and company restructuring, are on RadioShack's website, radioshackcorporation.com.

As for the remaining stores, RadioShack said it signed a purchase agreement with General Wireless, an affiliate of Standard General, to sell between 1,500 and 2,400 of the stores.

General Wireless is expected to work with Sprint to set up "store within a store" concepts.
